Background: Potato (Solanum tuberosum) popularly known as ‘The King of Vegetables’, has emerged as fourth most important food crop in the world after rice, wheat and maize. Indian vegetables basket is incomplete without potato as its, dry matter, edible energy and edible protein makes it nutritionally superior as well as staple food throughout the world. Methods: The experiment during 2016-2018 was laid out in factorial randomized complete block design with three replications to study the effect of bed size on the yield and size of the tuber under different irrigation methods. Results: Maximum yield was obtained in 60cm bed (narrow bed size) whereas in irrigation system drip produced maximum yield. All quality parameters did not influence due to sowing method and irrigation system but chip recovery was more in drip irrigation than furrow system. Maximum yield through interaction was found in drip irrigated 105 cm triple row bed. Around 45-50 per cent water was saved through drip irrigation as compared to furrow irrigation. However, maximum benefit cost ratio was obtained in furrow irrigated 60cm bed size.

Drip irrigation is basically precise and slow application of water in the form of discrete continuous drops, sprayed through mechanical devices, called emitters into the root zone of the plant. The field experiment on Impact of fertigation and drip system layout were conducted at Research farm at IFTM University Moradabad (UP). The experiment was laid out in factorial randomized block design with treatments. In chilli maximum yield of 812 g/plant which is worked out as 0.006 t/ha was observed for the treatment T2. Even though the yield for the treatment T2 was high and was due to the reduction in the quantity of material for drip irrigation system. At harvesting time, samples of green pepper fruits were randomly harvested from each plot to measure fruit length, fruit diameter. In addition, total weight of fruits in each treatment were recorded by harvesting pepper fruits twice weekly and then the total yield as Kg/fed., was calculated. The maximum yield of crop 900 gm/plant and minimum of yield 600 gm/plant and total yield 52270 gm (52.270 kg).

The integrated use of chemical and organic fertilizers can help in sustainable and environmentally sound nutrient management of soils. A study was conducted in the farmer’s field of Godaghari, Rajshahi from February to May 2012 to investigate the effect of integrated nutrient management on nutrient uptake by rice cv. NERICA 10 and economization of inputs. Six treatments viz. T1 = Control, T2 = RFD for MYG + cowdung @ 5 t ha-1, T3 = RFD for HYG, T4 = RFD for HYG + cowdung @ 5 t ha-1, T5 = RFD for HYG + cowdung @ 5 t ha-1 based on IPNS, and T6 = RFD for HYG + 10% excess fertilizer of HYG were used. The experiment was laid out in a randomized complete block design with three replications. Results showed that the uptake of N, P, K, S, Ca and Mg by both grain and straw of rice were statistically significant due to use of integrated nutrient management. The highest nutrient uptake was recorded from the treatment T5 and the lowest value was obtained from control. Combined application of cowdung @ 5 t ha-1 along with recommended chemical fertilizers based on IPNS was more economic compared to other treatments because maximum benefit cost ratio was calculated from this treatment. The overall results suggest that integrated nutrient management can be used as an alternate option of chemical fertilization to achieve maximum yield, nutrient uptake and cost of return for rice cv.

The experiment was conducted to find out effective control measure against thrips and pod borers of mungbean by various means, including chemicals, botanicals and biopesticide. The mungbean variety, BARI Mung-6 was grown in the field and six treatments viz., T1 [Azadirachtin (Bioneem plus 1EC)], T2 [Bacillus thuringiensis (Bt. powder)], T3 [Spinosad (Tracer 45SC)], T4 [Chlorpyrifos + Cypermethrin (Nitro 505EC)], T5 [Thiamethoxam + Chlorantraniliprole (Voliam flexi 300SC)] and T0 [Untreated control (water spray)] were set in randomized complete block design (RCBD) with three replications. The insecticidal treatment options showed significantly different performance against thrips (Megalurothrips distalis), gram pod borer (Helicoverpa armigera) and legume pod borer (Maruca vitrata) on mungbean. The lowest population of thrips, gram pod borer and legume pod borer was found in Voliam flexi 300SC treated plot which showed maximum percent reduction of these pests. The lowest percent pod infestation by pod borers observed by the same treatment. Bioneem plus showed the intermediate results considering all the parameters. The maximum yield (1254.50 kg ha-1) and the highest marginal benefit cost ratio (MBCR) (6.68) were obtained from Voliam flexi 300SC. Considering effectiveness and marginal benefit cost ratio, Voliam flexi 300SC was more effective among treatments for controlling thrips and pod borers of mungbean followed by Nitro 505EC. SAARC J.

A field investigation was carried out in farmer’s field at Pudhupalayam, TNAU, Coimbatore, during 2015, to improve the productivity of groundnut variety TMV 13 under drip and micro sprinkler fertigation system. The experiment was laid out in randomized block design (RBD) with three replications comprising of 11 treatments. Results indicated that maximum pod yield (3495 kg ha-1), haulm yield (6452 kg ha-1), harvest index (0.351) and shelling per cent (73.95 per cent) were obtained with drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T1). The water saving achieved under drip irrigation was 40.08% and 55.06% at 100% and 75% PE, respectively, whereas, under micro-sprinkler, it was 25.10% and 43.83% at 100% and 75% PE, respectively over surface irrigation. Higher WUE of 19.28 kg/ha-mm recorded under drip irrigation at 75% PE with fertigation at 100% RDF as WSF (T2) followed by drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T1: 15.88 kg/ha-mm). Highest NUE (23.30 kg kg-1 NPK ha-1) was recorded in drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T1). Drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T1) recorded higher gross return (Rs. 254353 ha-1) and net return (Rs.134712 ha-1). Whereas, the benefit cost ratio was highest in micro sprinkler at 100% PE with fertigation at 100% RDF as WSF (T6: 2.41). The margin benefit cost ratio (MBCR) was recorded highest under micro sprinkler at 100% PE with fertigation at 100% RDF as WSF (T6: 2.53) as compared to all other treatments.

A field experiment was conducted with the purpose of testing and evaluating the use of a closed-loop, real-time control system which was developed by (Elnemr M.K., 2017) for application to a poor hydraulic performance drip irrigation system with sandy loam soil cultivated with cucumber crop. This control system collects soil moisture data through three sensors distributed along each third of the lateral. The control system was based on calculating the average soil moisture content (MC) of the three readings and using it as an indicator to start or stop irrigation process according to the requirements of the plant. The control system will start the pump after the depletion of allowed MC percentage of available water which is one of the required inputs to operate the control system. The irrigation process continues until reaching the field capacity (FC) value. The study compared two management methods for the irrigation system. First one was using the proposed control system (Aum) and the other one was manual operation based on calculating water requirement from climatic data (Clm). Using the proposed control system led to increase cucumber crop production by 23.8% of Clm productivity. The control system led to save water and seasonal irrigation time. This led to increase water productivity and energy use efficiency of Aum if compared to Clm by 41.71% and 110% respectively. Despite the added cost to the irrigation system because of the control system, the benefit/cost ratio for Aum was higher by 24.39% due to the decrease in energy and labour costs in addition to the increase in crop production. The study recommended using the researched control system with drip irrigation systems which show poor hydraulic performance to reduce negative effects on crop production and to reach more efficient use for both water and energy with keeping the opportunity to increase benefit/cost ratio. Further studies should be done on the system with drip irrigation system that work under acceptable ranges of hydraulic performance. Also, further studies should be done to investigate the most effective and suitable distribution of the sensors along lateral.

ABSTRACT The objective of this study was to evaluate the productive and economic performance of a forage cactus and sorghum intercropping system in relation to a forage cactus single cropping system under different irrigation blades with saline water. The study was conducted in Serra Talhada, State of Pernambuco, in a randomized block design, consisting of a factorial arrangement with split-plot parcels (5×2) and four replications. The five plots were the irrigation depths based on the reference evapotranspiration (ETo) (0, 8.75, 17.5, 26.25, and 35% ETo) and the two cropping systems were single forage cactus cropping and cactus intercropped with sorghum. The experiment was conducted for one year, with one forage cactus cycle and two cycles of sorghum. Yields were obtained at the end of the cycles. Economic profitability was analyzed by means of net revenue (NR) and the benefit/cost ratio (B/C), with cactus forage sold as forage or as "seed" and sorghum as forage. Net revenue and B/C simulations were carried out over an eight-year useful life span of the irrigation system. Increasing irrigation depth increased the dry matter yield of the intercropping system because of higher sorghum yield. Based on the NR and B/C ratio values, forage cactus and sorghum produced as forage produced higher economic outcomes in the intercropping system and showed a higher profitability from the 2nd year of implementation of the irrigation system. Forage cactus and sorghum intercropping irrigated with saline water is therefore recommended for forage production in the Brazilian semi-arid region.

A field experiment was conducted at Agronomy Field Laboratory, Patuakhali Science and Technology University, Dumki, Patuakhali from July 2018 to November 2018 to evaluate the effect of sunflower residues and herbicides on the yield and economic performance of transplanted Aman rice. Weed control methods tested were T1 = weedy check (Unweeded control), T2 = Weed-free check by hand weeding twice, T3 = Pendimethalin, T4 = Pretilachlor, T5 = Butachlor, T6 = Pyrazosulfuron ethyl, T7 = Bensulfuron methyl + Acetachlor, T8 = Bispyriback sodium, T9 = 2,4-D amine, T10 = MCPA, T11 = Sunflower residues, T12 = Sunflower residues + 100% Pyrazosulfuron ethyl, T13 = Sunflower residues + 75% Pyrazosulfuron ethyl, T14 = Sunflower residues + 50% Pyrazosulfuron ethyl. The experiment was laid out in a randomized complete block design with fourteen treatments replicated thrice. Weedy check registered significantly the highest total weed density (354.67 m-2) and total weed dry matter (51.81 g-2) while weed-free treatment by hand weeding twice recorded significantly the lowest total weed density (6.67 m-2) and total weed dry matter 0.49 g-2) . Weedy check produced the highest weed index (34.24%) and hand weeding produced the lowest. Among different herbicides applied alone, butachlor had the lowest total weed density (15 m-2) and total weed dry matter (6.43 g-2) after hand weeding. Hand weeding recorded the highest grain yield (5.14 t ha-1) which was statistically similar to pendimethalin, pretilachlor, butachlor, bensulfuron methyl + acetachlor and sunflower residues + 100% pyrazosulfuron ethyl. Higher grain yield was attributed to a higher number of panicle m-2, number of filled grains panicle-1 and 1000-grain weight. The highest gross margin (22955 Tk. ha-1) and benefit-cost ratio (1.32) were obtained from butachlor. Integration of sunflower residues with pyrazosulfuron ethyl produced effective weed suppression and satisfactory yield comparable to butachlor. Although the integration is less profitable than butachlor the farmers can use this technology as a feasible and environmentally sound approach in transplanted Aman rice field. Bangladesh Agron.
